Do Thin Oils Destroy Engines? Lessons From GM's Massive Recall | Engineering Explained

[Dr.Kamiya]

So tl;dw:

GM has a massive engine recall going on. For affected cars they will inspect the engine. If the engine is already out of spec (i.e. damaged) they will replace it. If it isn't out of spec, they change the oil from 0W-20 to 0W-40. Apparently even with the inherent design or manufacturing flaw, having thicker oil is enough to keep the engines from failing. Scientific explantion follows on why thicker oil can be better (higher Hershey number etc.)

Some other interesting stuff mentioned, like spining the engine faster (revving higher) = more hydrodynamic lubrication. So yeah, revving is good pala!

Also explanations on how changing viscosity works. i.e. from 5W to 0W it's safe, likewise from a -30 to -40 also safe because the new oil falls within the range of the originally recommended oil, but not the other way around, but also why lower viscosity oil is no big deal if your engine was manufacturer correctly so I guess arguments for both??

Here's another one:


And why I insist on going higher up on the allowable viscosity than what the OEM 'recommends':
